BIOS package for the Dell Vostro 3910 desktop on Wistron board 222004-1, including images for both a 16 MB and a 32 MB flash chip. The 222004-1 number follows Wistron's numbering, the ODM behind this board. Systems of this generation may use two SPI chips, so match each image to the chip of the same capacity and program them with an SPI programmer. Read and save the original contents of each chip first so the service tag and system data can be restored. Check the board number printed on the PCB.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
